Abstract
Description
- The application pertains to apparatus and methods for self-testing of thermostats associated with a security system, or an environmental control system, associated with a commercial building or residence. More particularly, the application pertains to such apparatus and methods where confirmatory feedback signals can be generated by the thermostat for diagnostic or self-test purposes.
- The security space is evolving into Green solutions, home automation, lighting control and HVAC integration. The challenge going forward is that security dealers monitoring security systems in homes with integrated HVAC thermostats will be getting the calls when the HVAC system is not operating, whether it is caused by the security/home automation/thermostat or not.
- They will be spending money to investigate HVAC malfunctions not associated with the security system, home automation system, or thermostat, by having to send a service technician to the site to rule out the security/home automation/thermostat. Such unnecessary trips can become a significant expense.
-
FIG. 1 is a block diagram illustrating aspects of a system in accordance herewith. - While disclosed embodiments can take many different forms, specific embodiments thereof are shown in the drawings and will be described herein in detail with the understanding that the present disclosure is to be considered as an exemplification of the principles thereof as well as the best mode of practicing same, and is not intended to limit the application or claims to the specific embodiment illustrated.
- In one aspect, a thermostat can be integrated into a security system or home automation system (using wired, wireless, z-wave, ziggbie or other). The thermostat includes a self-test feature that can ensure that when the temperature is raised or lowered, whether on site or remotely, the proper thermostat relay is triggered/restored sending the proper signal to the HVAC equipment then responsible for heating or cooling. A message can be transmitted that the heating and cooling interface relays are functioning properly and when required. In such instances, HVAC malfunctioning usually resides in other parts of the HVAC system such as a blower, a boiler, air conditioner, or power to the boiler.
- In operation, a homeowner or business calls the central station complaining of HVAC issue. The central station can ask an on-site person to initiate a test, can initiate the test remotely, or simply monitor the indicators of a continual test.
- Central station personnel can then ask the on-site person to raise the thermostat set point above the actual temperature in the room or region being monitored. Conversely, the central station can raise the thermostat set point remotely without a local presence. When the thermostat is above the temperature, there should be the appropriate relay activation/deactivation (so in the summer, the cooling, for example air conditioning, function should turn on. In the winter, the heating function would turn off). The self-test would send a message indicating the actual state of the relay to the security system/home automation system which then transmits the message to the central station.
- Central station personnel, or the on-site person can then lower the set point temperature to ensure the relays switch state once again. In this way, the central station personnel can eliminate the need for a service call due to malfunctioning equipment beyond the scope of the equipment they installed and are monitoring. Advantageously, they can fully test the thermostat functionality, ensuring relay activation/deactivation for heating/cooling/humidity above and below a set point threshold.

FIG. 1 illustrates anoverall combination 10, in accordance herewith, which includes anenvironmental control element 12 which is coupled to aconventional HVAC system 14.System 14 includes heating andair conditioning sub-systems 14 a, b and aconnection interface 14 c.System 14 responds to control signals generated bycontrol element 12 as discussed below.Combination 10 provides heating, and/or cooling for a monitored region R, a residence or other building. -
Control element 12 can include one or both of a localsecurity monitoring system 18 a, and/or home or buildingautomation control system 18 b. Alocal thermostat 20, which monitors temperature in the region R, is in wired or wireless communication, indicated at 20-1, with one or both of thesystems 18 a,b. Thermostat 20, on a programmed, or non-programmed, basis couples heating or cooling control signals such as 24 a, b, via a heating signal output port and a cooling signal output port, to the heating andair conditioning units 14 a,b to heat or cool the region R as would be understood by those of skill in the art. - It will be understood that the specific details of
thermostat 20, except as described herein, are not limitations of the scope of the claims hereof. Embodiments implemented with various types of thermostats come with the spirit and scope hereof. Similarly, the details of any associated HVAC system are not limitations of the claims hereof. - In accordance herewith, the
thermostat 20 includes a heater switch, for example a solid state switch, or a relay, 20 a and an air conditioning switch, a different switch or relay, 20 b which provide the switchedcontrol signals 24 a, b to theHVAC system 14. In addition,thermostat 20 includescircuitry 20 a-1, 20 b-1 to generate feedback signals 22 a, 22 b indicative of the real-time values ofsignals 24 a,b. - The feedback signals 22 a, 22 b can be coupled or transmitted via
interface 20 c to the system orsystems 18 a, b to provide information to the system(s) 18 a,b as to the values or states ofoutput signals 24 a,b being coupled to theHVAC interface 14 c. Those feedback signals, received via communication link 20-1 can be evaluated at therespective security system 18 a, orautomation control system 18 b to determine if the switches, orrelays - It will also be understood that various circuits can be used to generate the feedback signals 22 a,b from
thermostat 20. For example, optical isolators, or operational amplifiers coupled to thecontrol signals 24 a,b could be used to generate the feedback signals. The exact details thereof are not limitations of the claims hereof. - The
thermostat 20 can include thetransmission interface 20 c which receives the feedback signals 22 a,b and forwards them, via link 20-1 to the system(s) 18 a,b. It will be understood that where the feedback message, or messages sent fromthermostat 20 indicate that thethermostat 20 is working properly, and theheating unit 14 a orcooling unit 14 b are not responding properly, service of one or both of those units may be required. For example, a defective boiler or furnace such as 14 a, or, a failure of power to the boiler or furnace, or a malfunction of theair conditioner 14 b may need to be addressed, quite apart from any of thesystems 18 a,b orthermostat 20. - The
structure 12 could also be in wireless communication, viaantenna 18 c andcommunication link 12 a, with a regional monitoring station S where monitoring personnel can respond to incoming messages fromstructure 12. In the event that individuals working or residing in the monitored region R contact the monitoring station S relative to performance of theHVAC system 14, the feedback signals 22 a, b provide diagnostic information as to where a problem might be located. - It will also be understood that the central station S might be in real-time, wireless communication with a plurality of environmental control systems 12-1, -2,-3 . . . -n comparable to the
system 10. As a result of being able to evaluate feedback from the respective thermostats, comparable tothermostat 20, personnel at the central station S will be able to more effectively and promptly provide preliminary assessments as to where maintenance is needed with respect to displaced, respective environmental control systems 12-1 . . . 12-n. - From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred. It is, of course, intended to cover by the appended claims all such modifications as fall within the scope of the claims. Further, logic flows depicted in the figures do not require the particular order shown, or sequential order, to achieve desirable results. Other steps may be provided, or steps may be eliminated, from the described flows, and other components may be add to, or removed from the described embodiments.
